Anup Sharma	43803cb16f	perf scripts python: Add support for input args in gecko script ... Refines the argument handling mechanism in the "gecko-report" script to enable better compatibility and improved user experience. The script now differentiates between scenarios where arguments are provided for record and report cases where gecko.py arguments are passed.

Anup Sharma	f9f72b2ab7	perf scripts python: Add command execution for gecko script ... This will enable the execution of gecko.py script using record and report commands in 'perf script'. And this will be also reflected at "perf script -l" command. For Example: perf script record gecko perf script report gecko Committer notes: As discussed on the perf tools office hours, I made -F 99 the default for the record script and removed the double -- on the report script so that the existing 'perf script' protocol for the combined operation: # perf script gecko Works, i.e. the record script pipes its stdout into the stdin of the report script, basically: /bin/sh /usr/libexec/perf-core/scripts/python/bin/gecko-record -F 99 -g -a -q -o - | \ /bin/sh /usr/libexec/perf-core/scripts/python/bin/gecko-report -i - Testing it: The resulting JSON file needs to be uploaded to https://profiler.firefox.com, Anup already has code to start a local http server on the trace_begin handler of the gecko python script, start firefox and feed it the JSON. The example below only collects sample for the specified workload, so that we don't produce thousands of lines, to collect system wide samples, use instead: # perf script gecko -a sleep 0.5 # nohup perf script gecko sleep 0.5 { "meta": { "interval": 1, "processType": 0, "product": "x86_64 GNU/Linux", "stackwalk": 1, "debug": 0, "gcpoison": 0, "asyncstack": 1, "startTime": 274601692.636,
